Business Layer; finLogRO object updated, added UserData property, optimised other properties

The finLogRO Business Layer object has been updated.

A new UserData property has been added.

How a number of other properties are loaded has been optimised. These properties are stored as XML, and therefore have to be loaded from XML - which is relatively slow. Previously this was done when the finLogRO was created. Now this is deferred until the property is used, hence they load a lot faster. The following properties have been updated:

AccountDataDate
Balance
BalanceOverdue
BalanceOverdueContractual
ExtendedDataNotes
ExtendedDataNotesHtml
StatementBalance
StatementDateTo
StatementDateFrom
StatementFinal
StatementMinimumPaymentDate
StatementMinimumPaymentDirectDebit
StatementMinimumPaymentTransactionPk
StatementMinimumPaymentValue
StatementOverdue
StatementOverdueLast
StatementPaymentNextDate
StatementPaymentNextDirectDebit
StatementPaymentNextValue
